My opinion is that the rules have become overly complicated, that is why I push Gurras proposal forth from time to time. When there is a rules book (a real size book), a case study book, third party rules explanation books, classes and I know what, and people still dont get the rules straight, there must be a better way to do it.
For example, this youtube film was linked to in norwegian sailing media today:

Getting a really simple ruleset would slash costs for events and our organizations, and make it easier on the sport. Other sports manage with far simpler rules, and I dont see why sailing should not be able to do the same.
